This invention relates to fountain ,pens

and in particular to One adapted for 'writing in different colors.

lA particular object of. my invention is to provide a penfhaving adouble point, the points to be used singly in the posting of gures orother work requiring contrasting color of writing fluid'. My pen isparticularly adapted for bookkeepingin that one lo of the pens may beused for 'posting some of the figures in red and the other pentmay beused for posting'some ofthe figures in yblue or black ink, the changefrom one to the other of the pens being vreadilyY made and at the sametime, the shape and size of sta-ntl ard types of pens being preserved.

A further object of my invention is to provide a simplifiedconstructiionfiwhich reduces the cost of manufacture and at the sametime to provide `a sturdy and leakproof construction which may made upatlowcost.

' A still further object ofi-ny invention is to provide a multi-colorfountain' pen which is self-filling and one in which the parts are $5 soarranged that mixing .of theldiferent colored inks'is prevented andpositive ow of each of the colors of infk is produ-ced.

Changes and variations may be made in the construction shownanddescribed without departing from the principles of the invention orsacrificing its chief advantages; hence such invention is not tobeconfined to the structures shown vthe accompanying drawing:

-Referring tothe drawing in detail, j5 indicates a body member providedwith a cen- (a `tra-l Opening 6 inthe'opposite Walls of the Opening ofwhich are provided,the circularseat 7. A screw bore 8 extendstransversely through the body 5 conc-entrically of said seat 7 and isarranged to hold in close con- 50 tact with said seat 7, the projectingportion 9 formed on a pen holder or rotor 10 that is 'snapped intoposition between the extended portions 11 of "said bodyv 5k. The'body 5is provided with the longitudinal bore 12 con 16u stituting ink passagesor flues which Open into the seat 7 and which at said point arelar-ranged to coincide With openings 13 'and 14 provided in` theextended portions 9 of the holder 10. This holder 'is shaped at its endsif. Aas at 16 -to conform to the xshaped end 17 lof the body 5 and wheneither of the pens 18 or 19 are projecting Ybeyond t'he vbody 5 and inposition for use, theholder 14 completes at the opposite sides of thebody 5 the shaped .end 17 of said body. 7 The holder 14 is provided withthe oppositely disposed bores 20 and `21 for the reception of the pens18 and 19 respectively together vwith their feeders 22, this portion eoof the pen construction being Well known 'in the art 'and thefeedersfbeing usually forced into a pen .end Opening to be held in placeand permit proper feed ofthe ink to the pen itself.v o i The bores 21and 20 connect with the openings 13 and 14 through the medium of thepassages 23 and 24 respectively so that-ink coming down through eitherof the passages 12 of the body ,5 will pass into either of the iinpassages 23 .or 24 depending upon which pen point 18 or 19 is in theoutward position ,and ready for use. In Figure 1, pen 18 is outermostand in position for use With the result that the passage 12 aligns withthe opening lus 14 and the ink Hows through the passage 24 tothe pen 18.Atv the opposite side of the holder, however, the passage or opening 13is closed by `reasonwof the fact that it Vdoes noti-register with theend of the opening 12 and I0@ hence, pen 19 is not being supplied Withink and being positioned Within the space 6 of the body, is not in useand is protected from damage by reason of its position Within the body5. Y v

In order that the passages 12 of the body may be supplied yWith ink ofdifferent colors, I have provided a sack holder 26, the ends of whichare of circular formation as at 27 and are provided with the outwardlyextending bosses 28 over Whichr snap the re stricted ends 29 of the sack30iand l31. The holder 26 is provided with av longitudinal bore 32constituting an ink passageterminating at one end at one side ofthe sackholder as at 33 and at the opposite end in theboss 28, positioned at theouter end of said sack holder 26. The holder is also providedwith an inkbore 34 extendingthroughY the innermost boss 28 and opening at theopposite side of the .holder fromthe passage 32'. These passages 32 and34 coincide with the ink passages 12 When the end of the holder 26 isseated in the recess 35 provided in the body 5 for that purpose. Thesackholder is preferably held in connection With the body bv a force itwhich renders the same leakproor and if necessary other means may beemployed to secure the ltwo parts together although they can be takenapart for cleaning.

The sacks 30 and 31are made of rubber and constitute reservoirs fordierent colored inks, the sack 30 for instance beingarranged to holdblue ink While ther sack 31 could .be used to hold red ink and they areencased in the barrel 3G which has threaded connection as at 37 to theupper end of the body 5, the barrel 36 being also threaded at its openend Where itengages the body 5 for the purpose of receivingthethreadcdend 39 of a cap 40. This cap 40, as is usual in fountain pens Vbears theclip 41 and its internal bore is reduced as at 42 to provide areceptacle for the pen when the cap is placed over the body 5.

An important feature of my inventionv is the use of the bolt 13 Whoseend is threaded as at 44 into a suitable ferrule l5 Which is countersunkin the body' and is flush with the surface of said body. .This bolt isadjustable to draw together the opposite Vsides or extensions 11 of thebody 5 and to securely hold in position the holder to prevent leakage ofink and at the same time permit rotation of the holder 10 to placeeither pen 18 or 19 in position for use and at the same time to aligneither'theopening'lll or the opening 13 With either of the channels 12so that the proper ink may be fed from either the sack or sack 31 to thepen to be used. f

In filling the pen, it is vsimply necessary to remove the barrel v36byu'nthreading the same from the body 5 and dipping each of thepens 18and 19 into proper colored ink, thefsacks 30V and 31 can be' manipulatedsuccessivelyto lill themselves by suction through the proper pen 18 or19 in the usual manner.

All of the parts of my pen construction may be made of hard rubber orcomposition With the exception of the pens and the bolt and ferrule, thesacks 30 and 31 being of the usual pliable rubber of the compressibletype employed as reservoirs in fountain pens.

It is evident, therefore, that I have provided a double duty fountainpen which may 'beemployed--to lWrite in contrasting colors -of-delay andtrouble and have lprovided a construction which lends itself readilytothe easy cleaning of the pen and quick separa-tion. of all of theparts for a thorough cleansing.

. My invention is not to be restricted to the precise details ofconstruction shown since `various changesA and 'modiiications may bemade therein Without departing from the e scope offthe invent-ion orsacrificing the advantages derived from' its use.-
